How to perform multiple image insert and upload in PHP?

Question

I want to add images goa.jpg, kerala.jpg, delhi.jpg using input type 'file' as multiple. The below code is working perfectly to insert single image.

Now I want to perform multiple image uploading using for loop but I am not getting the actual code without errors. Any one have any experience with this?

                $file_name=$_FILES["packageimage"]["name"];
                $temp_name=$_FILES["packageimage"]["tmp_name"];
                $imgtype=$_FILES["packageimage"]["type"];   if($imgtype!='image/jpeg'&&$imgtype!='image/jpg'&&$imgtype!='image/gif'&&$imgtype!='image/png'&&$imgtype!='image/bmp')
        {     $msg = "Please upload only Image file";   }
         else{ 
        $ext= GetImageExtension($imgtype);
                $imagename=date("d-m-Y")."--".time().$ext;
                $target_path = "../upload/products/".$imagename;
                move_uploaded_file($temp_name, $target_path);

// query to insert images.

        $query=mysql_query("insert into tbl_products set catid='".$catid."', packageimage='".$imagename."',  add_date=now()");
        if($query)
        {
        $msg="Product Added Successfull";
        }

When I am trying using for loop in above code it stores only first image and display only first image.

Please have look you can get all idea about multiple upload http://php.net/manual/en/features.file-upload.multiple.php

See bellow example

<?php 
print_r($_FILES);
?>
<form action="" method="post" enctype="multipart/form-data">
  Send these files:<br />
  <input name="userfile[]" type="file" /><br />
  <input name="userfile[]" type="file" /><br />
  <input type="submit" value="Send files" />
</form>

See Result is bellow

Array
(
    [userfile] => Array
        (
            [name] => Array
                (
                    [0] => cancelled booking - PAYG.png
                    [1] => cancelled booking - PAYG.png
                )

            [type] => Array
                (
                    [0] => image/png
                    [1] => image/png
                )

            [tmp_name] => Array
                (
                    [0] => C:\xampp\tmp\php402A.tmp
                    [1] => C:\xampp\tmp\php402B.tmp
                )

            [error] => Array
                (
                    [0] => 0
                    [1] => 0
                )

            [size] => Array
                (
                    [0] => 99134
                    [1] => 99134
                )

        )

)

For Your question following is foreach

<?php 
foreach ($_FILES['userfile'] as $position => $file){
    print_r($file);

}

?>

When Result for that See Bellow :

Array
(
    [0] => cancelled booking - PAYG.png
    [1] => cancelled booking - PAYG.png
)
Array
(
    [0] => image/png
    [1] => image/png
)
Array
(
    [0] => C:\xampp\tmp\php284D.tmp
    [1] => C:\xampp\tmp\php284E.tmp
)
Array
(
    [0] => 0
    [1] => 0
)
Array
(
    [0] => 99134
    [1] => 99134
)

So now you can understand

You can use multiple attribute to upload multiple files, like this:

HTML

<form action="upload.php" method="post" enctype="multipart/form-data">
  <input type="file" multiple="multiple" name="packageimage[]" />
  <input type="submit" value="Upload" name="submit" />
</form>

PHP

<?php

    if(isset($_POST['submit'])){
        // directory where the files will get uploaded
        $target_dir = "upload" . DIRECTORY_SEPARATOR . "products";

        // count the number of files uploaded
        $num_of_files = count($_FILES["packageimage"]["name"]);

        // loop through each file to upload
        for($i = 0; $i < $num_of_files; ++$i){

            // valid file extensions
            $valid_extensions = array("gif", "png", "jpg", "jpeg", "bmp");

            // get the file extension
            $ext = strtolower(pathinfo($_FILES["packageimage"]["name"][$i],PATHINFO_EXTENSION));

            // now check against permissible extensions
            if(in_array($ext, $valid_extensions)){

                // target file name
                $target_file = $target_dir . DIRECTORY_SEPARATOR . date("d-m-Y") . "--" . time() . "." . $ext;

                // upload file
                if (move_uploaded_file($_FILES["packageimage"]["tmp_name"][$i], $target_file)) {
                    echo "The file ". basename($_FILES["packageimage"]["name"][$i]). " has been uploaded. <br />";

                    // do your database operations here

                } else {
                    echo "Sorry, there was an error uploading your file.";
                }
            }else{
                echo "Please upload only Image file";
            }

        }
    }

?>

Sidenote: In order to provide cross-platform compatibility, you should use PHP's DIRECTORY_SEPARATOR constant to write path strings, e.g. "..".DIRECTORY_SEPARATOR."foo", because the way to do it on Windows would be "..\foo" while on everything else (Linux, UNIX, Mac OS X) it would be "../foo".
